A Star Trek series based on Hikaru Sulu is in the works.
Paramount saw the success of Star Trek: Strange New Worlds and decided to do the whole Leonardo DiCaprio meme with their next set of ideas, apparently. According to Giant Freaking Robot, one of the two new series in development is in fact a series based on Hikaru Sulu. As for right now, Giant Freaking Robot doesn’t have any more information on the project other than that, so it’s always possible this is just a working idea from Paramount at the time.
They do mention three directions the series could go and they all involve the actor. The actor will determine which Sulu and what time period this show takes place in. If they nab the original Sulu, George Takei, you could actually put the series in and around the time of The Next Generation or even Prodigy, as it’s quite common for human beings to live well into their 100s by this point in time.
They could go with the current Sulu actor, John Cho, which would put the series in the Kelvin Timeline, and may serve as a prequel or sequel to Star Trek 4, assuming that film ever gets made. Lastly, the show could lean on a new actor entirely, which would put it as a prequel or companion series to Strange New Worlds.
Star Trek should not be doing a Sulu series at this point
Sulu is a great character but with Star Trek 4 and Strange New Worlds two of the bigger projects in Paramount deck at the moment, it just doesn’t make sense to do a Sulu series at this point in time. There’s too much going on already in this franchise, the last thing fans need to figure out is what timeline or universe does THIS show fall into?
Most fans want more episodes from their shows, not a constant stream of new series. It’s not only wearing down the fandom but it’s also far more expensive to keep launching new series, than it would be to just add 10 more episodes to already established shows. Sure, Picard and Discovery didn’t work, and are both likely coming to, or already set to end but Lower Decks, Prodigy, and Strange New Worlds are hits, at least to varying degrees.
Star Trek should focus on those three core shows, and maybe a fourth depending on how long Lower Decks has left in it, and stop worrying about all of these other spinoffs, prequels, and sequel series.
